Well, it is a cost comparison. How much space is available. (Actually,
most resolvers are
bigger than modern optical shart encoders, so size is not likely to be a
problem.)

So, it boils down to how much would shaft encoders of suitable
resolution cost, vs.
how much does a resolver to quadrature converter cost?
